Abstract
There are described contact terminals which enable stable measurement of electrical characteristics of semiconductor devices. A heat-resistant insulating film having a plurality of apertures formed therein is sandwiched between an upper metal mold and a lower metal mold. The upper and lower metal molds are positioned, and conductive resin is poured into the cavity defined between the upper and lower metal molds, thereby producing a plurality of contact terminals. After removal of the upper and lower metal molds, there is produced a heat-resistant film having a plurality of contact terminals formed thereon.
